DeepSeek

In early 2025, DeepSeek caused quite a stir in the AI ​​world: a Chinese company released a model comparable in capabilities to leading Western counterparts, but significantly cheaper to develop. A mobile app provides direct access to this model, free and ad-free.

The assistant confidently handles a wide range of tasks: answering complex questions, writing and editing texts, parsing code, and helping with math and logic problems. DeepThink mode forces the model to reason step-by-step before responding, significantly improving its performance on complex queries. Files and images are supported, and conversation history is saved between sessions.

The main thing that sets DeepSeek apart from its competitors is that it's completely free with no limits on the number of queries. No subscriptions, no tokens, no hidden conditions.

However, there is a significant drawback: the "server is busy, try again later" message is familiar to most users. Server load periodically makes the app unavailable for several hours. The model sometimes replays during long conversations. Privacy concerns are also relevant: data is stored on servers in China, which is a key issue for some users.

A powerful tool at a zero price – with caveats regarding stability and data geography.

Features:

• Free with no ads, subscriptions, or request limits.
• DeepThink mode for step-by-step solutions to complex problems.
• Working with files, images, and saving conversation history.
• Frequent outages due to server overload.
• Data is stored on servers in China.
• Geolocation and personal information are collected and may be transferred to third parties.
